How to take down a lightweight concrete wall with minimal dust?

[anders07]

I have a wall piece of 60 cm that stands in the middle of what will become a closet. It was previously the wall to the closet but now I'm going to make the closet across the entire wall in the room...
At first, I thought about leaving the wall section since it will be "inside" the closet, but since it is 30 cm thick, it takes up quite a bit of space and the measurements become difficult to handle with it remaining (96 cm on one side and 136 cm on the other).

So this is what it looks like:
__________________________ Back wall
||........||..Closet..||
||.REMOVE==>||............||
||----------------------|| New sliding doors
|| .....................||
|| ........Room.........||

Since the room is furnished and lacks a door (as of now), I'm considering how to best remove the wall with minimal dusting.

Is it wrapping in plastic as best as possible and using an aerated concrete saw?

The alternative is a hammer and chisel... Which dusts the least, perhaps?

The wall is probably a mixture of Ytong and/or blue concrete as other aerated concrete walls in the house have been...

the aerated concrete saw and a vacuum cleaner as well as that you cover with plastic.

It goes surprisingly fast with a hammer and chisel if you want to minimize the dust.

A wide chisel bit in a hammer drill is effective and reasonably dust-free. Try to split at the joints between the aerated concrete blocks.

The aerated concrete saw quickly dulls if used for demolition. The mortar between the aerated concrete blocks and any plaster on the wall effectively kills the sharpness of the saw.

As mentioned, carefully cover the space with plastic and then install a negative pressure ventilation in the area that leads outside. For example, a cheap bathroom fan or duct fan that you connect with a ventilation hose to your plastic-covered area.

This way, you can create as much dust as you want in there without anything escaping into the other living spaces.

Wrap the area carefully as mentioned, and then set up a negative pressure ventilation for the space that leads outside. For example, a cheap bathroom fan or duct fan that you connect with a ventilation hose to your wrapped area.

This way, you can dust almost as much as you want in there without anything coming out into other living spaces.

Yes, well, thanks. I've tested that before, but it didn't work well because some leaked out, and now the room is so oddly situated that it's hard to get a pipe out.

A wide chisel in a rotary hammer is effective and relatively dust-free. Try to divide at the joints between the aerated concrete panels.

The aerated concrete saw quickly becomes dull if used for demolition. The mortar between the aerated concrete panels and any plaster on the wall effectively kills the sharpness of the saw.

There is both plaster and joints, and probably chicken wire as well, but I had planned to try knocking off the plaster with chicken wire by hand first and then cut the aerated concrete...
